1. Main jet are primarily responsible of fuel flow in middle range RPM
2. As RPM goes up A/C and E-tubes become more significant
3. At max throttle A/C has most effect on fuel flow
Would you guys agree?
A/c affect the mixture only at higher rpm WOT. On my weber 38 22r I notice the changes only above 4k. Main jets will affect the whole powerband mixture and highway cruising mixture as well.
